Very small on something already small is pretty much nothing...... The positive outweighs the negative so much its not even worth talking about but people will.
I don't see any positives in catching Covid when the more people that catch it the more it mutates in a way that's favourable to the virus, presenting a moving target to our immune system. This means reinfections galore and we are trusting to luck that it will continually mutate into a more benign form, but this is far from guaranteed as the virus' goal is increased transmission not lower severity per se.
It also makes it much harder from a vaccine point of view as they just can't keep up with an ever more infectious and immune evasive virus (unless the vaccines that work against all current and future variants come to fruition).
There are low effort things the government could do in terms of increasing ventilation, testing wastewater (sewage) extensively (much cheaper and easier than relying on LFTs to monitor the situation from their point of view, although LFTs should still be used so that people know if they are infected) and boosting sick pay and allowing those who want to work from home to do so by enshrining it in law. However, they are not doing them for ideological reasons and because they want to wish problems away.
When we get a pandemic with ten to fifty times the death rate I hope we don't make the same mistakes again. Also, the same applies to the climate emergency which is a much greater crisis than Covid if we again do not do enough to preempt it.
